TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 707,882, dated August26, 1902.

Application filed April 10, 1902.

To all whom, it may concern: 7

Be it known that I, J OHANNES HENDRIKUS VINK, a subject of the Queen of.the Netherlands, residing at Kleine Overstraat 45, Deventer,Netherlands, have invented certain new and useful Improvements inType-\Vriting Machines, of which the following is a specification.

The present invention relates to a typelever for type-writing machines,in which the types in their position of rest lie against aninking-cushion and on striking the key-lever are turned in such a waythat they apply the ink directly to the paper. This invention differsfrom known constructions of this class in that the type-baris pivoted toa lever so as to oscillate on an axis normal to the longitudinaldirection of the lever, and that this oscillating motion is produced bythe motion of the key-lever through the agency of a sliding rodconnected at one end to the frame and engaging at the other end in aguiding-slot in the type-bar carrier.

In the accompanying drawings, which illustrate the invention, Figure lis a side elevation showing the type-leverin its position of rest. Fig.2 is a front view of the same, omitting the bed, key-lever, and platen.Fig. 3 is a side elevation showing the type-leverin printing position.

The type-lever a is produced from a sheetmetal blank of suitable form bybending the two sides together on longitudinal lines, so as to bringthem in parallel position at right angles to the connecting back a Thisconnecting back is limited to the central part of the lever, leavingopen spaces between the sides at a and a. to permit the movement of theparts, as hereinafter described. At the upper part of the lever is aspecial type-bar carrier 19, pivoted to oscillate on the pin 61. On thistype-bar carrier is mounted a typebar 0 of suitable form, having one ormore types. The type-bar-carrier b is adapted to turn in the fork-likeupper end of. the typelever a and is provided with a curved guiding-slotf, which receives a slide f on the upper end of a rod g, extendingdownward and guided between the two sides of the lever a and pivoted atits lower end to a link i, which is pivotally connected to a standard onthe frame. The upper end of the rod g is guided Serial No. 102,256. (Nomodel.)

by its connection With the type-bar carrier 1) through the slidefandalso by a pin 0, fixed in an outward bend of the rod g and slidingagainst the back of the type-lever a, for which purpose the opening a inthe lever is provided. The lower end of the rod projects through theopening (t and is guided between the back a and a fixed transverse pinhiu the lever.

The type-lever a, is fulcrumed at its lower special projection on whichalso serves for pivotal attachment of the link t'. A rod Z, pivoted to abifurcated lug on the lower end of the type-lever a, communicates motionthereto from the key-lever m, which is pivotally fulcrumed on the bed ofthe machine and is pressed upwardly by a spring 1).

The operation of the device is as follows: The parts being at rest, asshown in Fig. 1. upon moving down the key-lever m the rodl is drawndown, and thereby the type-lever a brought to the horizontal position.(Shown in Fig. 3.) In this movement the rod t' draws down the bar g,which through the medium of the slide fproduces rotation of the type-barcarrier 1) on the pivot d, and the slidef, trav ersing from one end ofthe slot f to the other, turns the type-bar carrier 1) and with it thetype a through an angle of one hundred and eighty degrees on the levera. The device thus takes the position shownin Fig. 3. When the key-leverm is released, the latter rises under the influence of the spring P, thetypele'ver a is restored to vertical position, and the pressureexercised by the bar 2' on the bar 9 slides the latter upward and by thepressure of the guided bar 9 and the slidef, acting in thespecially-formed slot f, the type-bar is returned through an angle ofone hundred and eighty degrees to its first position. In the positionshown in Fig. 3 the types are turned downward and can print upon paperpassed over a roller or platen, whereas in the position of rest (shownin Fig. 1) they may lie against a suitably-arranged ink-pad. If the typebar is provided with a plurality of'types, as is shown in the drawings,then by adjustment of the platen-roller n one type or another is usedfor printing in customary manner. As

the mechanism for turning the type-bar carrier Z) can be so formed thatthe oscillating end on the bearing-block or standard 70,21.

7 carrier 1) pivoted to the end of the lever to; and the guided bar 9sliding in the cavity of the type-lever a, connected at one end by therod 11 to the standard 70 and at the other end to the type-carrier b andimparting oscillatory motion to said type-carrier by the movement of thelever a, as explained.

2. The combination of the standard is; keylever m; typelever a, andconnecting-rod Z pivoted to the standard 7c; oscillating typebar carrier1), having a curved slotf and pivoted on the free end of the lever a;type-bar c mounted on the carrier b;'sliding bar 9 connected at one endto rod 1 and guided in the lever a by pins 0 and h and the slidefworkingin the slotf and communicating, oscillatory motion to the type-barcarrier by the movement of the lever to on standard 70, substantially asdescribed. y

In testimony whereof I have hereunto set my hand in the presence of twowitnesses. J OHANNES HENDRIKUS VINK. WVitn esses:
